Answer:
I believe the answer is A - graph W
Step-by-step explanation:
It's a linear function: y = mx + b
We have (138; 112.96); (209; 142.78)
substitute the values of x and y to the formula of slope m:

Now we have: 
We must find b. Substitute the value of x and y from first pair of numbers:

Answer: y = 0.42x + 55
The final price is $135 , because
.10 × 150 = 15
150 - 15 = 135
3/16= 0.1875
Though if you mean 16/3 it is 5.333.....
